  SAP Error Message WT124
  Message Text:
  Replenishment currently being run for customer &1 by user &2
  
  Cause
  This message occurs when a replenishment process (such as warehouse replenishment or stock transfer) is already running for the specified customer (&1) and is being executed by another user (&2). SAP prevents multiple simultaneous replenishment runs for the same customer to avoid conflicts, data inconsistencies, or duplicate processing.
  In other words, the system detects that a replenishment job is currently active and locks further attempts to start another replenishment for the same customer until the first process completes or is terminated.
  
  When does it occur?
  
  When you try to start a replenishment run (e.g., via transaction codes like LT24, LT21, or custom replenishment programs) for a customer or warehouse that already has an active replenishment process.
  When the previous replenishment process did not finish properly or is still running in the background.
